There's alot to be had in the Olds motors with stroking. It'll make any combination come alive by stroking it out a little. Olds motors aren't known to need to spin high rpm's though. Most strip motors never see above 6k rpms. The street/strip guys often shift at 5k-5500, that's where out powerband is. An Olds BB will make good useable torque (on a properly built engine) from around 1k rpms to about 5k rpms.
